U need the HPL EC more than I do. I can see sludge balls on the parts.

Preventative Maintenance. No leaks, sludge, or oil consumption. My Venza has a 2GR-FE V6 is not known for oil consumption but cleaning up the piston oil control rings up for the next 120k. Note: The Toyota dealer just replaced the scheduled: iridium sparks, orig serpentine belt, pink coolant...

Your observation is correct. I saw a HPL passenger engine oil voa and the oxidation is around 20. The interesting thing is that the recommendation of 20% by volume of EC to engine oil has an equivalent oxidation 1 to 5 ratio (oxidation is in absolute/cm 20 vs 113) In other words, (20*5 qts +...

Gotcha, thank u again. I am re-posting the EC uoa. The oxidation is high and is expected for a cleaner. Typically, the oxidation baseline is around 20s for non-neglected uoa or a voa. HPL EC voa

Thank u for sharing. Wlk did u notice any engine cleaning using HPL EC among your vehicles?

When u say HPL, u mean HPL EC? Am I correct? I just bought 6 qts of HPL EC. I think Dave’s comment 30-90 days is conservative and errors on the side of caution.

I bought the car brand new in 2014 and have been doing oil changes every 5K mi.

Thanks, I will probably do less than 60 days to be on the conservative side and not to damage seals. In ur situation, did it help clean or loosen things up?

How much time or mileage elapsed before u did the oil change?

My Toyota V6 @120K does not consume oil and has been getting a 5K OC and a XG9972 Fram Ultra @10K. I am interested in preventative maintenance on the piston oil control rings. I asked Dave the following: Response: If it takes 30 -60 days to go 5000 miles - i would go the full interval. If...

Jackpot!

Thank u. Can someone who has subscribed tell me from their ‘managed subscription’ tab what is in their next shipment? What did it default to?

When I do the buy 2 and get 1 free and subscribe for a 6 month interval, what happens at the next shipment? Do I automatically get another buy 2 and get 1 free deal or does the subscription goes to qty 2 5qt jugs?

How do cancel the subscription later?

Thank u. Crossing my fingers that the Mobil 1 EP HM oil cleaned up ur piston oil control rings. U may want to install a new PCV so the crankcase pressure has some where to go.

What was past and current oil consumption rate? 1qt / 5K to 1/4qt / 5K. Am I correct?

Here u go. I don’t think he loosen the drain bolt or loosen the filter but dad is supervising. https://www.facebook.com/share/r/Zo3wmhtJfcRw1Bfv/?mibextid=UalRPS

Another data point, the Lexus dealer in the Philadelphia area charges $92 for a 6qt synthetic oil/filter change and u have to wait an hour. With a Fumoto engine drain ball valve, I turn the lever, have a 20 minute lunch and then swap in the new oil filter. Done in a total of 30minutes with a...

Very similar to the car care nut situation except for the fact the engine is different. Another piston oil control rings written all over it.

What I am doing is that I never put much faith in Toyota’s dealer 10k OCI recommendation. Both vehicles have a 5K OCI warning message despite the dealers recommendation to disregard the 5K warning. There are two observations. 1st on the Venza, I once did a 6.5K OCI and noticed a small of...
